This happened to me years ago near the University of Illinois campus (UIUC) with Comcast. I had multiple techs come out but they would only come in the morning when the connection was fine. I finally escalated to corporate who finally told me they needed a node split. I made them give me 100% free internet until the split was complete about 6 months later.
